CR has become an accepted method of imaging in general radiography, but has yet proven itself in digital mammography in the United States. The FDA only recently approved a Computed Radiography (CR) system for breast imaging from FUJIFILM Medical Systems. To date, it is the only one available. Pricing information would need to be obtained directly from them, as I am sure it varies depending on your specific needs.
CR is based on indirect technology. The indirect conversion detectors absorb x-rays giving off a cloud of light that is then detected by photodiodes. This diffused light has a negative impact on resolution and ultimately the overall quality of the image.
The Hologic Selenia digital mammography system uses direct technology, which eliminates the need to convert, x-rays to light, thereby generating an image directly from x-rays. The result is a sharp digital image, and better contrast with greater consistency.
